Question

Sameer bought 1600 bananas at ₹3.75 a dozen. He sold 900 of them at 2 for ₹1 and remaining at 5 for ₹2. Find his gain or loss percent

Answer 1

cost of 12 bananas = rs 3.75
cost of 1 banana = 3.75/12
cost of 1600 bananas = 1600*3.75/12= rs. 500
s p. of bananas
first case,
s.p. of 2 bananas = rs. 1
s.p. of 1 banana = rs. 0.5 
s p. of 900 bananas = rs.0.5*900 = 450
second case,
no.of bananas = 1600-900 = 700
cost of 5 bananas = rs. 2
cost of 1 banana = rs.0.4
cost of 700 bananas = rs 0.4*700= 280
total selling price = 450+280
= 730
c.pSo, their is gain 
gain percent = x
s.p.-c.p./c. p.*100 = x
730-500/500*100=x
230/500*100=46
x = 46% 
Therefore, gain percent = 46%

Answer 2

The answer is 46% it is really easy
